 // Get a reference to a build service
        IBuildServer buildserver = (IBuildServer)tfs.GetService(typeof(IBuildServer));

        IBuildDefinition[] buildDefinitions = buildserver.QueryBuildDefinitions(project);
        foreach (IBuildDefinition buildDefinition in buildDefinitions)
        {
            string buildDefinitionName = buildDefinition.Name;

            Console.WriteLine(buildDefinitionName);
            Console.WriteLine(buildDefinition.ProcessParameters.ToString());
        }

1. There is nothing wrong with your code. I have tested with your code and get XAML build definitions successfully. Just make sure you specify the correct team project to QueryBuildDefinitions(String).

2. .Net API can only get XAML build definitions. If you use new build definitions, you are not able to get the build definitions from a .net api.

3. It's suggested use REST API to get Build Definitions. REST API can get both XAML build definitions and new build definitions.

REST API to get a list of build definitions :

GET https://{instance}/DefaultCollection/{project}/_apis/build/definitions?api-version={version}[&name={string}][&type={string}]
